Why has the price on filter M increased almost doubled?
No, I would not recommend this to a friend.

easy peasy

Everything went as expected. Replacing the filter was easy. The old filter was filthy and dusty, which is nice to see because it means we weren't breathing that dust and stuff.

Technically Superior

I found your products technically superior and plan to use them in my house, in my travel trailer, and in my F- 150 Hybrid.
Gifted three to my daughter whose husband came down with COVID and was isolating in three rooms.
Gifted another one to a grandson who had a cat litter box in his room.
I do have one question, What's the best way to determine it's time to change the filters?

My lungs aren't what theybused to be Since I spent 2 weeks on a ventilator in April 2020 close to death from covid ,this air purifier is one of the smartest purchases I made since then,I keep it in my bedroom running 24/7 on the lowest speed 2 feet from my side of the bed and it's helped me so much as far as air quality in the room and better breathing during sleep time
